2 Claims.

This invention relates in general to hinges and more particularly to hinges constructed of light weight or light gauge sheet metal and utilizing prongs for the purpose of securing their leaves to the parts hinged together.

One object of the invention is to strengthen and stiffen the leaves and prongs of a hinge of this character and substantially enhance the holding or securing action of the prongs.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming a part of this specification and in which:

Figure l is a plan view illustrating a hinge embodying the present invention associated with hingedly connected parts of which fragments are shown;

Figure 2 is a View in cross section taken on line 2-2 of Figure 1;

Figure 3 is a view in transverse cross section taken on line 3-3 of Figure 1, the part with which the hinge is associated being omitted;

Figure 4 is a view in cross section taken on line 4-4 of Figure 3; and I Figure 5 is an elevation of one of the bent and set prongs viewed from line 5--5 of Figure 2.

Referring to the drawing the numerals 6 and 'l designate the hingedly connected parts which may be portions of the body and cover of a wooden box or any other structure in which the parts are to be hinged together.

The hinge embodying the present invention is designated generally by the reference character H and comprises a pair of leaves designated generally at B and 9.

The leaves 8 and 9 are of similar construction and their adjacent edges are provided with interfitting sleeve-like bearings or hinge barrels designated at H! and H through which the hinge pintle l2 extends.

Each of the leaves of the hinge has a body portion l3 which may be suitably ornamented and which is formed at each side with a wing I4. Integral with each wing I4 is a prong I5, each prong l5 being preferably extended at right angles to its wing and also to the body of the leaf of the hinge. Preferably each prong I5 is provided with a pair of points designated at I6 and l! which extend parallel to each other and in spaced relation.

Each wing l4 and prong I5 is provided with a pair of beads l8 and I9 which may be pressed up or down from the sheet metal constituting the structure and which extend across the top of the wing through the bend atthe juncture of the wing and the prong and down through the two points of the prong to the extremities thereof. 5 These beads substantially strengthen and stiffen the structure, facilitate the driving of the prongs, and enhance the holding action of the prongs in the assembly.

When the prongs have been driven through 10 the parts to be hinged together they penetrate the structure and project therebeyond and they are then bent in opposite directions as illustrated in Figure 5. Simultaneously With the bending of the points of the prongs the edge portion of 15 the prongs in between the points are upset as indicated at 2B in Figure 5. This stiifens and sets the prongs and also tends to maintain the points thereof in their bent position to provide a much stronger clinch and prevent withdrawal of the prongs under strain. By having the bead run over the bending line or bend at the juncture of the wing and the prong, distortion of the hinge at this point is precluded. a

It is to be understood that while the struc- 25 ture shown and described is the preferred embodiment of the invention, the fundamental feature of the invention resides in extending a bead across the leaf, through the bend at the juncture of the leaf and prong and down through the 30 prong, Preferably the prong is pointed and the bead extends to the extremity of the point. This fundamental feature of the invention may be even more advantageously employed where a double pointed prong is utilized and simul- 35 taneously with the bending of the points in opposite directions the body of the prong is upset so as to set the structure and provide a much stronger clinch. Various changes in the size, shape and arrangement of the parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Theinvention claimed is:

1. A hinge having a leaf of sheet metal, a double pointed prong integral with the leaf and extending at right angles thereto, said leaf and prong being provided with a bead extending across the leaf, through the bend at the juncture of the leaf and prong and longitudinally of the prong, the body portion of the prong between the double points thereof being upset in the assembly to seat the prongs, prevent spreading thereof and enhance the holding action thereof.

2. A hinge having a leaf of sheet metal, a prong integral with the leaf and extending at an angle thereto and provided with spaced points, said leaf and said prong being provided with beads extending across the leaf, through the bend at the juncture of the leaf and prong, longitudinally of the prong and to the extremities of the two points thereof, the points of the prong being bent in opposite directions in the assembly and the edge of the prong between the points being upset to set the structure and provide a stronger clinch.
